Curb Adapters
RTU Curb Adapters
What Is a Curb Adapter?
A curb adapter creates a seamless connection between your new rooftop HVAC unit (RTU) and the existing rooftop curb—the raised structure that channels airflow into and out of the building.
Many older buildings have curbs designed for outdated or discontinued units. Rather than replacing the entire curb, a curb adapter allows you to upgrade the system efficiently—saving time, reducing cost, and minimizing disruption to the building’s operations.
It’s a smart, precise solution that helps your retrofit projects run smoother—without reworking the roof.
